While following the tutorial I get "can't find crate for `test`" while compiling for unit test execution about rust-raspberrypi-os-tutorials

Hi,

specific to my tutorial, you would get this whenever rustc comes across a #[test] and not a #[test_case] as it is emitted by the macro (https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials/blob/master/13_integrated_testing/test-macros/src/lib.rs#L22).
I had this case while writing the tutorial and couldn't figure out whats going on. Turned out a third-party dependency that I pulled in through cargo had a macro that not only emitted code, but also a unit-test with it (it was the tock-registers). That was very hard to find.

I can't tell anything about building std with cargo, since I haven't touched that yet. Until now, just using the precompiled std for aarch64-unknown-none-softfloat is sufficient.

Closing this for now since no action on the issue.

Please reopen for follow-up questions.
